PATENT BENJAMIN P. SAUNDERS, OF yIATAN, MISSOURI.

CULVERT.

SPECIFICATION forming' part of Letters Patent No. 643,685, dated February 20, 1906.

Application led J une 26, 1899.

To all whom t may concern.-

Beit known that I, BENJAMIN P. SAUNDnRs, a citizen of the United States, residing at Iatan, inthe county of Platte and State of Missouri, have invented new and useful Improvements in Oulverts, of which the following is a specification.

My invention relates to culverts, and is designed more especially as an improvement on a culvert on which Patent No. 542,978 was issued to me on July 16, 1895, my object being to produce a culvert which may be constructed of equal strength, but more quickly than the culvert forming the subject of my former patent.

To this end the invention consists in certain novel features of construction and arrangement, as hereinafter described and claimed, and in order that the invention may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1 is a view mainly in side elevation of a-culvert constructed in accordance with my invention. Fig. 2 is'an end view of the Fig. 3 is a detailed perspective View of the head-ring. Fig. 4 is a vertical longitudinal section showing the preferred method of attaching the internal tie-rods. Fig. 5 is a side elevation, partly broken away, showing a modified form of construction. Fig. 6 is a top plan view illustrating the construction of a curved culvert.

In practice this culvert, like the patented one, is adapted to be placed a sufficient distance below the surface of the ground to be removed from all chance of breakage due to the concussion by the weight of passing vehicles.

Referring to the drawings,where like reference-n u rnerals designate corresponding parts, 1 designates a series of pipesl flanged at one end, as shown at 2, so as to provide the seat or shoulder 3, the shoulder of one pipe form'- ing a seat for the smaller non-flanged end of the adjacent pipe,which,being also externally embraced by the flange, prevents their moving laterally.

In Fig. 1 the lian ged ends of the pipes, or at least one of the end pipes of each gang of pipes, or, if the culvert be a short one, one of the end pipes of the culvert, is provided with a plurality of holes 4, (one only of which appears,) said holes extending obliquely from above the flanged external end of the pipe toV Serial No. 721,822. (No model.)

the seater shoulder 3. One or more of the pipes are also provided with one or more branch conduits or arms, shown in this instance as consisting of the pipes 5, 6, and 7, coupled to= gether and adapted to be cemented or otherwise secured, the pipes 5 by preference being formed integral with the section or pipe 1, from which they project. These branch conduits or arms extend upward and outward in order to carry off the water at the opposite sides of the roadway.

This culvert can be readily used in a washout without, as is usual, digging out the bed of the washout to correspond with the known angle of the culvert. Vith this culvert it is only necessary to cut the ends of the pipes 1 at an angle or bevel necessary to cause them to conform to the angle of the washout, so as to avoid the necessity of deepening or filling in the washed-out points to correspond with the angle at which the culvert extends.

The gang of pipes forming the culvert are connected together by tie-rods. In Fig. 1 the tie-rods 8 are arranged as shown and extend near one end through the holes 4, and their heads 10 engage and rest upon the seat or shoulder 3, being held reliably in such position by the clamping-nuts 11. Secured by the clamping-nuts firmly against the opposite end of the culvert is the head-ring 12, which headring is provided with a series of external lugs 13, having holes 14, through which the external rods 8 extend, and a series of internal lugs 15, having holes 16 to receive internal tierods, presently referred to.

Referring to Fig. 4, it will be noticed that the pipe corresponding to the pipe 1 of Fig. 1, provided with holes 4, is provided with recesses 18 in shoulder 3 to receive the hookterminals 17a of internal tie-rods 17. Saidinternal tie-rods at their opposite ends project through the holes 16 of the internal lugs 15 of the head-ring, the threaded ends of said rodsbeing engaged, as before, by the clamp ing-nuts 11 to hold the pipes reliably together. It is obvious that the head-ring 12 may be applied to either or both ends of the culvert. In Figs. 1 and 4 it is represented as applied at the unfianged end of the terminal section of pipe. In Fig. 2 it is shown applied to the ianged end.

. In Fig. 5 a modification is shown, in which IOO an external tie-rod of adjustable construction is provided, 19 designating a pair of similar rods provided with hooks 20 at their outer ends, one of the hooks engaging the nonilanged end of one end pipe and the otherengaging the flanged end of the other end pipe. Said hooks have their threaded inner ends connected and engaged by a turn-buckle 2l, whereby the sections are clamped tightly and reliably together. Assuming that all of the pipes are molded With the holes 4 and with the recesses 18, it is obvious that the tie-rods can be used to connect the culvert-pipes together with facility in less time than is required where the tie-rods are threaded and must be engaged by clamping-nuts at both ends. It is also obvious that the head-ring, provided with perforated internal and externallugs, is of universal application in the construction of a culvert of this character.

Having thus described the invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a culvert, a series of connected pipes each having one end flanged and the other unlanged, said pipes being arranged With their unflanged ends fitting in the flanged ends of the adjacent pipes, in combination with a head-ring adapted to abut against either or both ends of said series of pipes, said ring hav'- ing outwardly-extending lugs containing perforations to engage a series of external tierods, and inwardly-extending lugs containing perforations to engage a series of internal tie-rods, said tie-rods extending from end to end of said culvert, substantially as set forth.

2. In a culvert, a series of connected pipes as described, in combination with a head-ring adapted to abut against one end of said series of pipes, said ring having outwardly-extending lugs containing perforations to engage external tie-rods, and inwardly-extending lugs containing perforations to engage internal tie-rods, both said series of tie-rods being secured at one end to said plate, and, at the other end, the external rods passing through openings in the flange of the pipe to seats on the inner shoulder of said flange, and said inner rods having hooked ends to engage recesses in said inner shoulder, substantially as set forth.

In testimony whereof I aiix my signature in the presence of two witnesses.

BENJAMIN P. SAUNDERS.
